Reduce number of retries in Bluetooth stack

FWLog (1)_formattedByTC.txtHi, I am sending data to one of the characteristics from nRF51 to the App(the problem happens in both iOS and Android). This is what I am observing: I send data to a characteristic once in 30 seconds. But, instead of sending data once in 30 seconds, the nRF51 sends data once in 30 seconds, then sends data 60 times in the next 30 seconds, then, once in the next 30 seconds, then, 60 times in the next 30 seconds, etc.

I think this is happening: If the App does not ack back to the nRF51, then, the nRF51 retries the send and that's why it is sending 60 times every 60 seconds (which is undesirable).

Is there a way to reduce the number of retries in the nRF51 side? Thanks.
